Abstract

The operation of a fossil-fueled thermal system is quantified by obtaining a reference fuel chemistry before on-line operation, and thereafter operating on-line. In on-line operation, a set of measurable operating parameters is measured, including at least effluent concentrations of O and CO , and optionally the concentration of effluent H O and the concentration of effluent SO . An indicated Air/Fuel ratio is obtained, as are the ambient concentration of O , and air pre-heater leakage and dilution factors. The fuel ash and fuel water are calculated, and the complete As-Fired fuel chemistry is calculated. From the complete As-Fired fuel chemistry, the pertinent systems parameters such as reference fuel heating value, boiler efficiency, system efficiency, fuel flow rate, total effluent flow rate, individual effluent flow rates, and individual emission rates are determined in a fully consistent manner. The Method has been reduced to software which is fully benchmarked and operational.
